The fuel pump was changed recently by a previous owner, I noticed a gas leak when I filled the tank. First it looked like it was the filler tube(not the issue). Then I checked the fuel pump I noticed that the fuel filter/regulator was allowing gas to flow out of the tank. I have dropped the tank twice pulled the fuel pump, pump looks good. Everything else looks good but the filter/regulator is still leaking gas. I've put new o rings on it, liquid gasket, still leaks. Has anyone else has this issue?
